Abstract (en)
[origin: EP3319226A1] A servo amplifier including an encoder for detecting rotation of a servomotor (11), a servo amplifier (13) for performing feedback control of the rotation of the servomotor based on a count value (hereinafter referred to as an "encoder value") of the encoder, and an amp control section (17) for controlling operation of the servo amplifier, wherein the amp control section sends an initialization instruction for initializing the encoder to the servo amplifier in a state of fixed cycle connection over a servo network between the servo amplifier and the encoder when an error occurs with the encoder. The servo amplifier performs initialization of the encoder without disconnecting the servo network when receiving the initialization instruction sent from the amp control section.
